Scores of dairy farm workers and activists marched Saturday to a Ben & Jerry’s factory to push for better pay and living conditions on farms that provide milk for the ice cream maker that takes pride in its social activism.

Protesters said Ben & Jerry’s agreed two years ago to participate in the so-called Milk with Dignity program, but the company and worker representatives have yet to reach an agreement.

“We can’t wait any more. We are going to pressure them and see what happens,” said Victor Diaz, a Mexican immigrant now working on a farm in Vergennes.

The march that began Saturday morning in Montpelier ended mid-afternoon at the plant in Waterbury, about 14 miles away. Organized Will Lambek said the marchers presented a letter to company CEO Jostein Solheim who said the company was committed to joining the program.

Ben & Jerry’s spokesman Sean Greenwood said before Saturday’s march from the Statehouse to the Waterbury factory that the company was eager to reach an agreement and negotiations were underway.

“We are a values-led business. We frame ourselves as an aspiring social justice company,” said Greenwood. “We try to do good with everything we can with our business. Dairy has definitely been one of those issues we have done a ton of work on for decades.”
